MACHINE FOR CUTTING LEAEEER.

.Specification of Letters .Patent 1Y0-:4216, v@letsel September.28,1837- To all whom 'it may concern Be it known that I, LEVI N, LELAND,of Grafton, in the county of Worcester and Commonwealth ofMassachusetts, have invented a new and useful Machine to be CalledLelands Patent Leather Cutter, and that the following is a true, full,and exact description of the same, referring to the drawings hereuntoannexed.

The machine is designed to be set in a frame A, A, in the drawing, whichpresents a side view of the frame and machine, which view, owing to thegreat simplicity of the parts of the machine, is deemed sufficient for afull understanding thereof. This frame may be made of wood or castingsaccording to the kind of work to be done and power applied.

B, B, are upright posts set into the frame, which sustain the arbors.

C, is a crank attached to the end of the arbor, to which the power isapplied, and which gives the first motion. At each end of this arbor isafliXed a small gearing, which, by means of a corresponding gearing ateach end of the cylinder D, communicates motion to the whole machine.The gearing in the drawings and model accompanying these specifications,are single, that is one gearing at each end of the arbors. For thepurpose of increasing the power of the machine, this gearing may bedoubled, that is by having a like set outside of the post-s, and whichmay be of different dimensions. The large cylinder, D, is sustained bythe post B, and a corresponding post on the other side of the machine.In these posts is inserted a sliding box, in thev center of which is theend of the arbor to the large cylinder. This bo-X is designed to slideup and down, and is regulated by the screw E, and by a spiral springunderneath the same. By means of this screw the cylinder may be elevatedor depressed at pleasure.

F, F, F, are bars sustaining the posts and there are corresponding barson the opposite side of the machine.

The gearing 0f the cylinder, which may be varied lin different ways forincreasing power, communicates motion to the carriage G. Upon each sideof this carriage are the racks II, I-I, which receive a horizontalmotion vfrom the gearing of the cylinder, and the carriage to whichthese racks are fastened, receives the same motion. This carriage restsand moves upon the rolls I, I, I,

I, In thisl carriage is placed the slide AI-I, vwhich receives the. samemotion with the carriage. The carriage ismade so large asl to receiveslides of different dimensions, according to the kind of work which istobe done. In the slide are inserted the knives with their edges upward.These knives may be made of different forms anddimensions, according tothe pattern to be cut, and may be elevated or depressed, and otherwiseregulated by means of screws in the sides of the slide. That is to say,the knife is elevated or depressed by means of a screw in the undersideof the slide;v the end of the screw presses up or elevates the knife andthen by reversing the motion of the screw, the knife follows it. down,and thus the knives may be so adjusted as to present a perfectly evenand horizontal surface upon which the leather rests.

The ends of the knives as they are inserted in the slide, are let into agroove in a piece of brass or other metal, and this piecel of metaladmits of a lateral motion upon the slide. thus receives the knife,there projects a screw through a mortise in the side of the slide, uponthe end of which screws are nuts as represented by L, L, &c. Thismortise is long enough to give all the lateral motion to the knives thatmay be desired, and by means 0f turning the nuts at the, ends of thescrews, the knives may be made fast at any4 point you wish, and thus thewidth of the pattern to be cut may be regulated at pleasure. All whichfully appears from the model herewith presented at the Patent Ofice. Theframe, posts, cylinder, carriage and slide, may be of wood or metal,according to the power to be' applied and the kind of work to be done.

Motion is given to the whole machine, by applying the power of whateverkind to the crank C. This causes the cylinder D, to revolve, and at thesaine time the carriage with the slide in it receive a horizontal motionand pass directly under the cylinder, and the leather is placed betweenthe cylinder and theedge of the knives, and thus the patterns are cut,and drop underneath the machine.

The more particular application of this the cutting of soles for shoesand boots, but it may be apfplied with equal advantage to thecutting 0From this piece of metal whichany other patterns of leather,

paper or cloth, and the inventor claims a right, and the benet of suchapplication accordingly.

To illust-rate the operation of the. inachine for the particular purposeabove referred to, take a strip of sole leather of a Width equal to thedesired length of the sole to be cut. This strip of leather is placedsmooth upon the upper surface of the carriage and slide. The crank C, isturned. This carries the carriage and slide, With the leather restingupon its surface, and upon the edges of `the knives, directly under thecylinder D. The cylinder presses the leather down upon the edge of theknives, cutting out a piece of leather of the precise pattern of theknives. These pieces of leather pass down between the knives, and thusthe work is done, and the machine ready to receive another strip ofleather.

The whole machine described in the foregoing specications, so far as Iam advised is new, but Y That l claim as my invention, and desire tosecure by Letters Patent, is

The cylinder in connection with the carriage under it, the slide placedin the carriage, and the knives inserted in the slide,

and the inode of regulating them as parin the specifications. Y
